Anaerobic ammonia oxidation reactor and process for treating high-ammonia nitrogen coal-to-liquid wastewater

The invention discloses an anaerobic ammonia oxidation reactor and process for treating high-ammonia-nitrogen coal-to-liquid wastewater. The anaerobic ammonia oxidation reactor comprises a reaction tank body, a pH detector is arranged on a water inlet pipe, an alarm is installed outside the reaction tank body, the pH detector is electrically connected with the alarm, and wastewater pH adjusting equipment is installed inside the reaction tank body; the wastewater PH adjusting equipment comprises a PH adjusting device; a gear adjusting device; a lifting device; and a guiding device. The arrangement mode that the PH adjusting device and the gear adjusting device are matched is utilized, a PH adjusting agent in the PH adjusting device is conveniently extruded out through rotation of the gear adjusting device, so that the PH value in wastewater is neutralized, the PH value is adjusted to 8.0-8.4, high activity of anaerobic ammonium oxidation bacteria can be guaranteed, and the anaerobic ammonium oxidation bacteria
